After posting to 'Early 70's Calculators'
I suddenly had the idea to use this area to try and
generate an archive of programs for the Texas Instruments Programmable Calculator family.
I will post some for my TI-51-III
's just as soon as I find them
I hope there are others reading this who may also be able to contribute.
Code: Select all
Factorials for the TI-58/59 from the Wiki
LBL A You'll call the program with the A key
STO 01 stores the value in register 1
1 starts with 1
LBL B label for the loop
RCL 01 by n
DSZ 1 B decrements n and back to B until n=0
= end of loop, the machine has calculated 1*n*(n-1)*...2*1=n!
INV SBR end of procedure

What an excellent idea!
I have recently acquired a TI58c and a TI59 complete with a PC100Cprinter cradle. I also own a SR56 which uses very similar codes; programs for the SR56 work quite well on the TI58/59 machines.
I used the SR56 in the late 70s for a lot of statistical work in my biology teaching. I even had it running a model population in 100 program steps. These machines helped me to learn machine code programming as their simple instruction set was very low level.
I also 'went modern' and acquired a TI66 that is almost program compatible with the TI58/59 series albeit very much slower but its batteries last for years.
